Synchronizing Axes

My standard chart consists on an independent axis (e.g. Depth on the left axis) and two dependent axes (e.g. Pressure and Temperature) plotted on the two horizontal axes. The dependent axes are usually set to Automatic scaling to handle the pressure and temperature data range. To make the graphs loo...
